Temperature Sensor Concept
May 19 , 2023
1、Temperature Temperature is a physical quantity that indicates the degree of heat and cold of an object. Microscopically, it is the intensity of the thermal motion of the molecules of an object. Temperature can only be measured indirectly by certain characteristics of the object as it changes with temperature, and the scale used to measure the value of the object's temperature is called the tempe...

Fluid Sensors for EV Thermal Management
Apr 27 , 2023
On a macro level, thermal management of EV batteries goes beyond temperature sensors. When monitoring the health of an EV battery, leak detection is essential, whether the vehicle is charging or on the road. Leaks of any kind can directly affect the battery or the system that keeps its temperature in the right range for optimal performance. 1、Liquid coolant Instead of circulating throu...

EV sensor technology extends, optimizes battery life
Apr 27 , 2023
Sensor technology throughout the battery pack is key to maintaining the battery in the short and long term. Sensor technology allows the thermal management system in an EV to start working as soon as it registers a temperature outside of the comfort zone range. Temperatures that are too hot or too cold can have a similar effect on EV batteries and their health. Excessive temperatures can affe...

Electric Vehicle Thermal Management
Apr 26 , 2023
Thermal management has been an issue for as long as there have been engine-driven vehicles - because the temperature of the engine and surrounding components can affect the performance and safety of the vehicle. Beyond normal thermal thresholds, the consequences of poor thermal management can be as inconvenient as overheating, or even as devastating as a fire. Electric vehicle thermal management i...

New energy vehicle battery temperature management and temperature sensors
Apr 26 , 2023
What is the biggest enemy of electric vehicle batteries? Extreme temperatures. Lithium-ion batteries perform best in the 15-45°C temperature range. Temperatures above that can severely damage the battery, while lower temperatures can reduce the output of the battery cells, thus reducing range and available power. The thermal management system always works to monitor or maintain the internal batter...

What is the difference between 2, 3 and 4 wire RTD temperature sensing?
Mar 31 , 2023
What is the difference between 2, 3 and 4 wire RTD temperature sensing? The difference between 2, 3 and 4 wire RTD temperature sensing is the accuracy of the measurement. Using 2 Resistance Temperature Detector (RTD) sensing provides good accuracy (possibly), 3-wire sensing provides better accuracy, and 4-wire sensing provides the best accuracy. There is also the option of using a Wheatstone bridg...

Electric Vehicle Thermal Management System
Mar 31 , 2023
Electric Vehicle Thermal Management System TMS is generally used for batteries that operate at high discharge rates, especially large battery packs that require long life cycles (>10 years) and are costly to replace. For example, due to high battery maintenance costs, high vehicle costs per SE and relatively low vehicle replacement rates, all HEVs, PHEVs and EVs must be equipped with a T...

Electric vehicle sensors need to monitor fast charging
Mar 31 , 2023
Electric vehicle sensors must monitor fast charging The safe and efficient starting and stopping of fast EV charging is ensured by sensor technology. Fast charging requires fast-responding sensors - primarily vehicle temperature sensors. Without real-time monitoring to trigger the system to maintain the ideal temperature, the risk of thermal damage to EV components increases dramatically. EVs need...

Battery pack sensor applications for new energy vehicles
Mar 31 , 2023
Battery pack sensor applications for new energy vehicles New energy vehicles all have the same characteristic - they all have battery packs. The internal structure of the battery pack is similar in that they all have a battery, a box for the battery, a high-voltage wiring harness, a low-voltage wiring harness, a high-voltage isolation system, a battery management system, a thermal managemen...

Temperature control method in cold chain transportation of vaccines and other drugs
Feb 27 , 2023
The most important thing for cold chain transportation is temperature control in the process of transportation. Temperature monitoring is controlled by a temperature controller. Long-distance transportation is usually equipped with a GPS temperature monitoring system, so that the temperature changes can be seen in real time in the office. Usually a refriger...
